Anisotropic Impedance Cylindrical Metasurface for Self-Adaptive Cancellation of Scattering of TE, TM and Circular Polarized Waves

The 2D problem of plane wave scattering on the model of an anisotropic impedance cylindrical metasurface (CMS) is studied. The scattering matrices of the CMS were obtained in the linear and circular polarization bases. A diagonal impedance tensor is synthesized, which provides that the fields of scattering of TE-, TM-polarized waves as well as two circular co-polarized waves are antiphase. The problem of synthesizing two CMS reactances with self-adaptive (to the irradiation frequency) cancellation of TE, TM, and circular polarized waves in the low-frequency region is solved. It is shown that the radar cross-section (RCS) reduction is from 60 to 10 dB in an ultra-wide range of ka values from 0.02 to 0.4. The scattering characteristics of two models of camouflage coatings are calculated. It is shown that the reactance CMS based on meta-particles in the form of rectangular strips reduces the RCS by 10 dB in the low-frequency band of 200–520 MHz with the incidence of the TM polarized wave and by 5 dB in the band of 480–720 MHz in the case of TE polarized wave.
